Overview:The Modular Smart Array 500 is a storage system designed for single and multiple path two-node clustering as well as direct attached storage (DAS) with up to 4 server nodes. Providing high data availability at SCSI economics the Modular Smart Array 500 offers superior data protection and increased uptime with redundant controllers power supplies and fans and Multipath software option to provide multiple I/O paths to the same logical volume. Because Modular Smart Array 500 is SCSI based there are no Fibre Channel infrastructure requirements such as hubs switches and cables allowing for significantly lower initial investment when compared to FC-SANs. Armed with DtS (DAS to SAN) technology theMSA500 adaptive infrastructure permits seamless conversion from SCSI protocol to the fibre-channel basedMSA1000 for additional scalability.
